Abstract (en)
An optical recording medium includes a first recording member (31) having a first light-transmissive substrate (31S) and a first semi-light-transmissive information area (31M) disposed on a surface of the first light-transmissive substrate, and a second recording member (32) having a second substrate (32S) and a second reflective information area (32M) disposed on a surface of the second substrate. The first recording member (31) and the second recording member (32) are joined to each other with the transparent layer (33) interposed therebetween with the first and second information areas facing each other. <IMAGE>
